METH D AND DENTAL DEVICE FOR REGISTERING BITES.

Application filed October a, 1927; serial No. 223,584.

ments of the condyle, and obtaining facebowv measurements all in one oeration.

More specific features of the invention will be noted from thespecifications and claims as hereinafter set forth.

The full nature of the invention will be understood from theaccompanying drawings and the following description and claims: d

Fig. '1 is a central vertical section taken thru a portion of thejawshowing the device in rest position. Fig. 2 is a plan viewlook ingdown upon from the jaw. V 1

In the drawingsthereis "shown anupper jaw 10 and a lower jaw or mandible11, with the gums 12 protruding inwardly therefrom,

Positioned over the gums there is a mass of.

prepared waX or substantially'plastic material 13 and 14. l

The device comprises a pair of concave'by convex thin metal plates 15and 16. Said plates are formed with surfaces of the same curvature andare positioned between the gums and the plastic material 13 and 14 sothat the coneave surfaces of both platesface the upper jaw andthe convexsurfaces the lower jaw. The plates in outline, as shown in Fig. 2-,conform substantially to the curvature of the gums, and, when inoperative position, same. On the exterior surfaces of each of theplates, when positionedtogether, there are curved ribs 17 protrudingtherefrom adapted to be embedded in the plastic material 13- and 1 1.Also there are provided reinforcing ribs 18 for strengthening the platesand main; taini'ngthem in conjunction with the ribs 17 intheir properform.

Protruding outwardly from the plates and positioned slightly to one sidethereof there.

are a pair of tongues 19 and Q-Ojfor'ming therebetween the slot 21. fSaid tongues are so arranged as to protrude from the front of protrudesubstantially beyond thev the-mouth when the plates are mounted be-'tween the jaws.

For the purpose of clamping the plates in their adjusted position afterthey have been manipulated, as hereinafter set forth, there is a clamp22 provided with ase't screw 23 which is adapted to clamp over the endsof the tongues 19and :20 of'both plates for securing" them rigidly inadjusted position with respect to each other. Said clamp 22 is providedwith a suitable projection 123 with set screw 24 cooperating with anopening 122therethru into which the rod 25 of a faeebow may be secured.

In operation, the usual 14 are formed and. inserted in the patientsmouth and corrected for height and fullness bite wanes 18 and I in theusual manner. With the prepared bite waxeswarmed to a soft or yieldingtempera- '-ture, afterhavingb'een so corrected, they are reinserted intothe mouth and-the plates 15 and 16are superimposed withrespect to eachth d i wh n r m v d ether and placed'between the warm bite waxes.fThe'patient is then directed toclose the mouth, with just suflici'entforce to compel the warm bite waxes to take the curved tinned until thepatient finally arrives at the natural tired rest position ofthemandible.

The patient is then instructed not to move the aw, and the clamp 22 isagain mounted 111 place and the plates are then locked in position. Ifthe dentist then chooses to do so, I

the facebow measurements may be taken by inserting. the rod 25 of thefacebow of the usual and well-known type in place and clamping it by theset screw 2 1. he plates are then removed from the mouth, either withorwithout the bite waxes, since the ribs 17 have registered theirposition with "respect thereto so as to permit reassembling. Thev entireassembly'of the plates and the bitewaxes, and if desired, the fa'cebow,are installed in the usual type of articulating frame 7 in the mannerWell known.

The clamping member 22 is then'removed,

and the mechanical condyles oi: the articulating frame are adjustedtocorrespond with all. the movements of the natural condyles of thepatient, as: recorded in the was bites and the position of the platesWith respect to each other.

It Will be readily understood by those familiar with dental practice,that by this method ofobtaining occlusal data, the device operates incopying the individual movements of the mandible inielllitllllfil'SiHlllfil to'the action of the pantograph. Thusorientation, the anterior component, are taitlr fully andauton'iaticallyrecorded by the position and action of the plates intheartic ulzu tor. Thns the articulator is readily adjusted tocorrespond to the particular torn'iation and each oi the patients aws,hereby the construction of artificial teeth therefor may be readilyaccon' plished. v

The, invention claimed is Y 1 1. A device of the character describedcomprising 'a pair o tconc'ave byvconvex bite plates with surfaces ofsubstantially the same curvature so as to seat one withinlthe other,said plates being adapted to have slidingcontact. in' all directions,and means for, clamping-said plat-es] in adjusted position.

2. A deviceof the character described comprising a pair of concave byconvex plates having substantially the-same curvature and adapted toseat one ithin the other for permitting relatively sliding move'mentsinall directions, means; formed on said plates for engaging andregistering them with a, suit.-
